What if the same private key shares two r values that are (almost) identical to each other? Does this help calculating the private key in any possible way?
Suppose r1 = cabc3692f1f7ba75a8572dc5d270b35bcc00650534f6e5ecd6338e55355454d5
r2 = cabc3692f1f7ba75a8572dc5d270b35ba54694a2d2302093d8b0a93ed5d83f2c
Here r1 + r2 from the same private key shares only their first 128 bits.
if you mean this, then you are wrong. R value must be the same in 1 wallet address with 2 different transactions. and if you have a script to auto calculate, maybe i can send you the script.

A few hours ago you were wondering how to use brute force applications, now you are a cryptography expert?
